Right click the mouse, navigate to System Setup > Network Setup > select DHCPand click Enable as shown in the figure below. Askpeople who secured the WiFi (who set password) to enable the NVR to connect.Answer:a.

If step a is not working, probably your router disabled DHCP or block new devicesfrom connecting.What DHCP does is: when router find new device connected, DHCP allocate new IP tothe device and connect it to the Internet.An easiest way to know if your router enables DHCP:When you connect a new device to your WiFi for Internet service (or a visitor/ friendwanted WiFi connection), does it require WiFi password only? If only passwordrequired, then your router has DHCP enabled if that requires not only password butalso some settings, then your router is secured from connecting new devices.
